A lot was learned, but the courses can be confusing especially the database normalization bit. I had to watch a few youtube videos to better understand it. Some of the assignments lack clarity and there wasn't enough editing done before the course was published; a decent number of errors in some of the questions asked. I had to skip the Week 5 Chinook practice lab because it lacked enough information to even attempt the task. I jumped on this course from a Python course taught by Prof Severance and it's such a difference. That course has someone actively going over assignments and responding to questions in the forum, so the lessons learned are not just from the already informative videos but also in the discussion forum.

Despite some of the many issues, I've learned a decent amount of information that I can build upon. Definitely read through the shared reading materials as many of them go further into breaking down the subjects taught, if you plan to take this course.

I tried other SQL courses before sticking to this, and many did not include practical tasks that will help you apply what you learn as you progress through the course. It would have a great bonus if the lab courses were graded too along with someone helping guide students in the forum.

I plan to finish the entire certification package before jumping into Prof Severance's Postgre course for a deeper understanding of sql usage.
